DIE FOR BRlCK-PRESSING MACHINES.

SPECIFIGATIGN forming part of Letters Patent NO. 692,353, dated February 4, 1902. Application filed February '7, 1901. Serial No. 46,339. (No model.)

To (LZZ whom it may concern:

Be itknown that we, KARL RIEDEL and HER- MANN SOHIEGNER, subjects of the German Emperor, and residents of Rockendorf, Germany, have invented certain new and useful Improvements in Dies for Brick-Pressing Machines, of which the following is a specification.

This present invention relates to dies for brick-pressing machines, the object being to provide an improved die in which the water admitted into the die to prevent the material from adhering to the walls is forced throughout the entire die to carry with it the deposits in any one of the water-conduits in contradistinction to the ordinary constructions in which the water-conduits are arranged independently, whereby the water admitted into one conduit is not forced to pass through the succeeding conduits, which can therefore be easily obstructed and cause damage.

The invention consists of the arrangement of a spiral or winding conduit leading from the basetof the die to the top thereof and having its side opened to the interior of the die.

In the accompanying drawings, Figure 1 is a vertical longitudinal section on line A B, Fig. 2. Fig. 2 is a top plan 'view of the improved die. 7

The die may be made of any desired form, material, and dimensions, in accordance with the kind of bricks or stones to be pressed or manufactured.

1 designates a water-conduit leading from a point near the base of the die on a spiral or winding line along the inner walls of the die to the top thereof. The lower end of the conduit 1 is connected to a water-inlet cock 2, While the upper end of said conduit is connected to a water-outlet cock 3. The side of the conduit is open to the interior of the die, as clearly shown in the drawings. Said conduit is covered in the usual manner by means of overlapping blades 4, slightly set apart from each other to enable the Water to flow from the conduit 1 into the die along the brick or stone pressed into the latter. Said blades 4 are only shown on the side walls in Fig. 1 for the sake of clearness and for the purpose of a better showing of the winding water-conduit 1.

In operation the water is admitted through the inlet 2, whence it passes through the winding conduit 1 and downward along the sides of the article pressed into the die and is finally discharged through the outlet 3, carrying with it the materials deposited at any point of said conduit.

Having fullydescribed our invention, what we claim, and desire to secure by Letters Patout, is-

In a die of the class described, the combination with the walls of the die, of a continuous winding water-conduit leading from the bottom to the top of the die along the inner walls thereof and having one side opening to the interior of the die, and an inlet at one end of the conduit, and an outlet at the other end of same, and overlapping metal blades covering the open side of the conduit, substantially as set forth.

In testimony whereof we have hereunto set our hands in presence of two witnesses.
